Santronics 3000 Ultimate AC Sensor 50-1000VAC

The Santronics Ultimate AC Sensor is a hand-held device for determining the presence or absence of 50-1000 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches and other voltage-carrying electrical systems. It is not necessary to disconnect the system in question because no contact is required for operation and current flow is not necessary to locate voltage. Simply touch the plastic tip to a connection point or move it along a wire. If AC voltage is present, the tip will glow red and you will hear an audible tone.

The Ultimate AC Sensor operates very much like the AC Sensor 3115, the choice of OSHA. The Ultimate AC Sensor has a new feature, an audio alert! You not only get a visual alert, but an audio alert as well. Another important feature of the Ultimate AC is that the audio alert reacts only to an AC voltage field, and will not beep when it comes in contact with a static field.

There is no ON/OFF switch on The Ultimate AC Sensor. Switches can wear out over time or even malfunction. Because the Ultimate AC Sensor has no switch it is always ready to use!

The QL Series II is the latest and highest performance linear regulated power supply series from TTi.
Single and triple output models are available. Each model can be specified with or without digital remote control interfaces.

Each main output provides more than 100 watts of power, and dual range capability offers higher currents at lower voltages.

New features include an enhanced auxiliary output with fully variable voltage and higher current capability on T models, and an LXI compliant LAN interface on all P models.

Building upon success
The original QL series re-defined the laboratory power supply in terms of precision and performance. Now the QL Series II builds upon that success and adds new features and models.

Exceptional precision
The QL series offers an unparalleled level of precision. Voltage and current are controlled using instrumentation quality 16 bit DACs enabling voltages to be set to 1mV resolution even at full output voltage. Indeed, the accuracy is sufficient for the QL to be used as a calibration source for some hand-held DMMs.

Multiple ranges for greater flexibility
The QL series II provides multiple ranges for increased current capability at lower voltages. The QL564, for example, is a 112W PSU with three ranges. The main range offers 0 to 56 volts at up to 2 amps. The higher current range provides up to 4 amps for voltages up to 25V. A further low current range provides an enhanced current setting and measurement resolution of 0.1mA.

Unrivalled performance
The QL series uses pure linear technology and offers unrivalled performance in terms of regulation, output noise and dynamics. Line and load regulation are close to the limit of measurement. Recovery time from transient current pulses is better than 50µs. Differential output noise is less than 350µV rms in CV mode and down to 20µA rms in CI mode. Of equal importance for critical applications in areas such as telecoms is common mode noise current (the noise current flowing between the output terminals and ground). This is less than 4µA rms on the QL Series – dramatically better than most other PSUs.

The TSX Series of High Output DC Power Supplies Power with Precision & Simplicity

The Thurlby-Thandar TSX series represents the state of the art in high output PSU design.
A wide range of voltage-current output combinations will become available with power levels of 360 Watts and more.

Each output combination is available in two versions: with conventional analogue controls.

The standard versions
The TSX series represents the state of the art in high output PSU design. A wide range of voltage-current output combinations will become available with power levels of 360 Watts and more. Each output combination is available in two versions: with conventional analogue controls (TSX) and with programmable controls (TSX-P).

Linear post regulation for unrivalled performance
The heart of all TSX series PSUs is an innovative regulator design which combines switch mode pre-regulation with linear post-regulation

The pre-regulator uses specially developed techniques to dramatically reduce the capacitance between input and output thus eliminating the high levels of common-mode noise normally associated with switch mode PSUs.

The linear post-regulator combines very low levels of output noise with excellent load regulation and transient response. The result is performance comparable with a pure linear design.

Compact and lightweight
The hybrid regulator design provides a PSU which is both smaller and lighter than competitive products.

The high thermal efficiency also means that the PSUs are silent in operation since fan cooling is unnecessary *.

Rear Power Terminals

Power output terminals are duplicated on the rear panel for rack mount applications or other situations where rear connection is more appropriate.

Digital Remote Control

To meet the varying needs of today’s engineers, a comprehensive array of interfaces is provided. RS-232, USB and LAN (Ethernet) with LXI support are provided as standard. An additional GPIB interface is also optionally available.

Each of the digital bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage, current and status. The interfaces are at ground potential and are opto-isolated from the output terminals.

RS-232

An RS-232/RS-423 interface is provided for use with legacy systems. This type of serial interface remains in common useage and is perfectly satisfactory for the control of power supplies because data speed is not an issue.

USB

USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use. A USB driver is provided which supports Windows 2000, XP, Vista and Windows 7 (including 64 bit versions).

LAN-Ethernet with LXI

The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct connection to a single PC. This interface supports LXI and is the most appropriate for larger system use because of its scalable nature.

LXI Compliance

The LAN interface is compliant with LXI-C. LXI (LAN eXtensions for Instrumentation) is the next-generation, LAN-based modular architecture standard for automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems. For more information on LXI and how it replaces GPIB, or operates along side it.

IVI Driver

An IVI driver for Windows is included. This provides support for common high-level applications such as LabView*, LabWindows*, and HP/Agilent VEE*.

GPIB (option G)

Further versions of the products, are fitted with a GPIB (IEEE-488) interface in addition to USB, RS232 and LAN.

Isolated Analog Remote Control

PLH-P units include isolated analog voltage control of both voltage and current. Analog control outputs (non-isolated) are also incorporated to enable easy parallel connection of multiple units in a master-slave configuration. Terminals for remote on/off control are also provided.

PLH-P Additional Facilities

From the front, PLH-P models are identical to standard PLH models and retain all of their manual control features.

The rear panel carries RS-232, USB and LAN (Ethernet) connectors, together with isolated analog in and non-isolated out for voltage and current, plus remote on/off control. Power output terminals are also duplicated on the rear panel.

All models can be additionally fitted with a GPIB interface (option G – factory fit only).
